A Christmas episode of "The Liberace Show" from 1954. This series featured piano player Liberace. The episode contains him mostly playing the piano with a handful of singing moments. Uploaded in 512Kb format because of my extremely slow internet connection.

Several notes on this episode:
This episode features some editing. Exactly how much or what kind, I cannot say as I am not sure.
The episode, along with the Piano playing, also features a utterly unexpected spoken-word segment.
His Piano playing skills are very good if a bit flashy and overly "populist".
He comes across very well, and I am glad to say this was before he had become a self-parody.
We also get to meet his family and stuff. There is one moment near the end that might offend those who watch videos purely looking to be offended by something. Those who take it as it is (a fluffy music show) will probably not be offended.
